The Fire Information for Resource Management System (FIRMS) of the National Aeronautics and Space Administration (NASA) uses satellite observations to detect active fires and thermal anomalies. They deliver this information to decision makers in near real-time (within 3 hours of satellite observation). This dataset includes active fires of the last 48h. Each point represents the centre of a 375 m resolution pixel where a fire was detected. It is updated twice daily. Compared to other coarser resolution (≥1km) satellite fire detection products, it provides improved response for smaller fires, improved mapping of large fire perimeters, and better detection at night, when fire activities usually occur. Consequently, the data are well suited for use in support of fire tracking and management (e.g., near real-time alert systems), as well as other science applications requiring improved fire mapping fidelity.
